Amid the growing demand for sustainable energy storage, biomass-derived porous carbons have emerged as eco-friendly alternatives to conventional electrode materials. This study shows that activated carbon prepared by one-step activation exhibits an enhanced specific surface area and pore volume. The optimum parameter ameliorating structural electrochemical properties is 60 min of microwave heating. area, volume, mesopore volume resulting (EUAC1-60) achieve 1589.0 m2/g, 0.82 cm3/g, 0.28 respectively. EUAC1-60 exceptional defect degree with I D/I G value 0.92 can provide ample active sites ion storage. investigation has highest capacitance 232.92 F/g at a current density 0.2 A/g. In addition, continuous cycling performance 1 A/g validates its stability retention 89.90% Coulombic efficiency 117.21% after 10,000 cycles. zinc hybrid supercapacitor cathode Zn foil anode displayed excellent 95.58 W h/kg power 64,800 W/kg. research presents innovative approach fabrication high-performance materials from Eucommia Ulmoides Oliver, demonstrating promising potential in applications.
